Thanks Korry,
After much investigation, your example:

UPDATE domain SET settings = settings || 'default_language:' || defaultlanguage || ';';

gave me what I was looking for after all. at first i didn't think so but after looking into it further (and a few smoke breaks to clear the head), i discovered it was correct. Thanks a lot.

Thanks Korry,
I think that's a step in the right direction but I'm not quite there yet. I'm trying to run this series of commands:

sql> UPDATE domain SET settings=CONCAT(settings, 'default_language:', defaultlanguage, ';');
sql> UPDATE domain SET settings=CONCAT(settings, 'default_user_quota:', defaultuserquota, ';');
sql> UPDATE domain SET settings=CONCAT(settings, 'default_groups:', defaultuseraliases, ';');
sql> UPDATE domain SET settings=CONCAT(settings, 'min_passwd_length:', minpasswordlength, ';');
sql> UPDATE domain SET settings=CONCAT(settings, 'max_passwd_length:', maxpasswordlength, ';');
sql> UPDATE domain SET settings=CONCAT(settings, 'disabled_domain_profiles:', disableddomainprofiles, ';');
sql> UPDATE domain SET settings=CONCAT(settings, 'disabled_user_profiles:', disableduserprofiles, ';');

When I did it this way:

 UPDATE domain SET settings = ('default_language:en_US;default_user_quota:10240;default_groups:;min_passwd_length:0;max_passwd_length:0;disabled_domain_profiles:;disabled_user_profiles:;');

It created one line in the column with everything strung together. 

I'm trying to get everything into individual lines. When I run separate statements using your approach, it created two lines (I think because one of the other tables, defaultuserquota, contained two values itself. 

So I'm still stuck. Does anyone else have any clues? Or am I totally mis-thinking this completely? Thanks.

      Is there an equivalent command (string) for this
        example:

        UPDATE domain SET settings=CONCAT(settings,
          'default_language:', defaultlanguage, ';');

        that works and accomplishes the same thing in postgresql
          v8.4? Thanks.

    The concatenation operator is available in 8.4, is there some reason
    that won't work for you?

    UPDATE domain SET settings = settings ||
      'default_language:' || defaultlanguage || ';';
